Edelbrock Ecu

21. Karl tucked the Edelbrock ECU up high on the interior side of the firewall. The ECU can also be mounted underhood, but given that Karl’s ’47 has no hood, that option wasn’t viable, since the processor must be kept dry. We’re not delving into the details of wiring for the fuel pump and distributor, as each application will differ, but if you take the time to follow Edelbrock’s well-illustrated instruction booklet, you’ll have no problem at all. The company also has toll-free phone tech support, should you have any questions.
